In Great Britain April 16, 1935 26 Claims.

This invention relates to apparatus for dispensing liquids and more particularly to apparatus for mixing liquid (such as sirup) from a bottle with liquid (such as water) from a supply source.

The object of the invention is the provision of an improved apparatus of this character and the invention consists broadly in the combination of a bottle holder mounted on a base in such a way as to be adapted to turn over from a normal position at which the bottle is upright to a delivering position at which the bottle is inverted, and a tap or cook so arranged and connected as to deliver the liquid from the supply source at the same time as the liquid from the bottle, the delivery of the two liquids being in the correct predetermined proportion.

In order that the invention may be the more clearly understood an apparatus in accordance therewith will now be described, reference being made to the accompanying drawings wherein:

Figure 1 is a front elevation of said apparatus, showing two bottles in the normal position and another in the inverted position.

Figure 2 is a side elevation of the same, showing a bottle in the inverted position.

Figure 3 is a reproduction in section to an enlarged scale of the lower portion of Figure 2.

Referring to the drawings the same illustrate an apparatus which constitutes a means for supporting a number of bottles I in a normally upright position from which they may be inverted by rotation about an axis xx, and a means whereby, when any bottle is so inverted a stream of the sirup contents is liberated through a valve fitting 2 which covers the mouth of said bottle, and simultaneously a stream of water is liberated through a pipe 3. The streams discharge in the correct proportions so that when a measure of beverage is required all that is necessary is to locate the vessel, invert the appropriate bottle until said vessel is filled with the sirup and water to the required extent, and then permit the bottle to swing back to the upright position. It will be noted that the act of inverting the bottle will agitate the sirup so as to mix adequately its constituents of different densities.

Each bottle is carried in a frame or holder which pivots about said axis ar-x, said frame or holder consisting of a shallow cup 4 in which the base of the bottle rests, a pair of arms 5 connected at one end to diametrically opposite points of said cup and at the other end to diametrically opposite points of an externally screw threaded ring element 6 located just beyond the mouth of the bottle, the aforesaid valve fitting 2 which passes through said ring element and engages the mouth of the bottle in the manner of a stopper, and a milled nut l in screwed relation on said ring element 6 and having a flange 8 engaging a flange 9 on the fitting 2, so that when said nut l is tightened, the bottle is gripped between the cup 4 at one end and the valve fitting 2 at the other. As shown said Valve fitting actually enters the mouth of the bottle, having a flange Ill whichrests, with a washer II in between, on the rim of said bottle.

The pivotal mounting of said frame or holder is effected by means of trunnions l2 carried by the arms 5 and resting in bearing slots in the upper ends of upright supports I3. The shallow cup 4 is loaded with a partial lead filling so that when the holder is released it will always swing back to the normal upright position.

The valve fitting 2 is formed with a longitudinal flow passage l4 through which the sirup is adapted to flow, and a transverse valve passage l5 which intersects said flow passage and in which the valve element I6 is adapted to reciprocate. A valve rod l'l secured to said valve ele ment l6 extends to the outside, and a spring 18 is in compression between the valve fitting 2 and an enlarged head IS on said valve rod, in such a way that said valve element is biased to the position shown in Figure 3 at which the flow passage I4 is closed. When the bottle is swung to the inverted position said enlarged head I9 engages a fixed stop 20 as shown in Figure 3, and as the movement of the bottle is continued, the spring [8 is compressed and the valve element l6 moves to the right hand end of the passage l5 thereby opening the flow passage 14 and permitting thesirup to flow.

The valve fitting 2 is also provided with an air passage 2| which is intersected by said valve passage I5 and from the inner end of which an air tube 22 extends to the base end of the bottle. An auxiliary valve element 23 integral with the valve element It is provided which at the normal position of said valve element closes said air passage 2l, and, as said valve element opens said flow passage I4, opens said air passage 2| thereby admitting air to the base end of the bottle to replace the sirup.

In construction it will be seen that the valve passage is bored completely through the valve fitting 2 and is closed at its two ends by means of caps 24.

As the bottle is swung back to its normal position, the valve element IE will instantly return to the closing position, and, in order to prevent the sirup in the extremity of the flow passage I4 beyond said valve element l6 from being thrown out by centrifugal force, a small longitudinal groove 25 is formed in the inner periphery of the valve passage l5 so as to establish a connection between the extremity of said flow passage and the right hand end of said valve passage after the valve element is at the closed position. By virtue of said valve element moving to the closed position a suction is set up at this right hand end of the valve passage which will serve to draw the said sirup from the extremity of the flow passage into said valve passage. A very small vent hole 26 is formed in the cap 24 closing the right hand end of the valve passage I 5 so that in due course the pressure in said valve passage becomes atmospheric.

The stream of water liberated through each pipe 3 flows from a common conduit 21 and through a passage 28 which is normally closed by means of a valve 29 and is opened when the .respective bottle is swung to the inverted position, by the valve fitting 2 of said bottle engaging the transverse member 30 of a unit pivoted about an axis 3|, which unit carries an adjustable presser member 32 which engages the projecting extremity of a valve rod 33 secured to said valve 29. As will be clear from Figure 3, the unit carrying the presser member 32 will, as the bottle moves to the inverted position, be rocked to the left about its axis 3| and the presser element 32 will force the valve 29 leftwards to the open position.

As will be clear from the drawings, the conduit 21 is formed in an integral'part of the basic supporting structure of the apparatus which includes the upright supports l3 and comprises a flange 34 for mounting the apparatus to a vertical wall.

The valve 29 moves Within a valve chamber '35 which is supported directly from said basic supporting structure and carries the pipe 3. The construction of said valve 29 and valve chamber 35 will be clear from the drawings, it being observed that said valve is biased to the closing position by means of a spring 36.

The communication between the conduit 21 and each passage 28 is through a restricted hole 31 as shown in Figure 3 and screws 38 are provided which project radially into said conduit to an adjustable extent so' that the extremity of each partially closes'to an adjustable degree the respective hole 31. Thus the rate of flow of water through each pipe 3 can be preselected to suit the particular sirup in the respective bottle.

The construction of the pivoted unit comprising the member 30 and carrying the presser member 32 is clearly shown in Figures 1 and 2. This unit forms one rigid whole and consists of a frame portion of which the member '30 forms the upper frame member and a disc shaped portion 39 in which the presser member 32 is screwed and which is formed with a lug 49 pivotally mounted between lugs 41 integral with the valve chamber 35.

The numeral 42 designates the port by which the Water is supplied to the conduit 21.
